750F2 ...airbox...or pod filters
« on: July 29, 2018, 11:53:03 AM »
My project bike is on the way, but I know it has not got an airbox and had some grotty pod filters which will not be left in place. They don;t look fit to filter air let alone dirt .... but the question is...what's the best route to go.

Originality says airbox, but I have had a brief trawl on E-Bay and not seen any F2 items for sale. Obviously, I would need a set of carb-box rubbers too as well as an element. Are these crafted from rocking horse poop...or just one of those thigns that come up if you look long enough?

She is going to get a light cafe racer makeover, so I could go for pod filters again, but I have had issues with these things in the past. Admittedly it was with CV carbs, which do not mix well with pod filters unless you like an overly rich midrange and lots of popping on the over-run...as well as wet running issues. I understand slide carbs are a bit easier to setup ass they are less reliant on intake pressure to work right. That was with old school K&Ns before the foam 'Ramair' type came out as well. Either way....I won't be looking at the cheap Chinese unbranded ones.

I also have no idea if the jetting is stock...but will be looking at the matter when I pull the carbs apart for a thorough clean and check. Somewhere in the shed lurks an old set of vacuum gauges too, which will need fresh pipes but should work.

That fits an F2?

Saw it but as it only listed Ks I moved on. So much to learn!

Here you go there are a few scratches but nothing visible when on the bike.
Its not distorted like most the crap on eBay and has all its internals minus the filter itself.

One is a 405 and one is a 392. Maybe another member can confirm  ;)

Me thinks Haynes 66 has a F2 in bits at the moment, he should be able to confirm  ;)
